i have seen a screen funal used on the opening of a brick or block wall where the bees are going in. it lets them out gut not back in. if i do thid and sit a brude box close to the exit, will the bees wind up going in the box? will the queen come out after bost of the bees come out of the wall? if the queen does not come out what do you do with the bees that did? i do not want to cut the block wall open.
